Recently built a Raspberry Pi system, and after initial setup, ran emerge -uavDN world -- got two blocks because module-init-tools and kmod are blocking each other. Note that both are part of the system profile 8O and result in warning to that effect if you unmerge them -- I got bold and unmerged module-init-tools anyway. Checked the ebuilds, and confirmed that kmod has
Code:
RDEPEND="!sys-apps/module-init-tools  ...

and module-init-tools has
Code:
RDEPEND=    ...
    !sys-apps/kmod


Please advise... do I need both? if not, which should I have? (why are both in the system profile if they are not both needed?) or basically, what do I do now?

Thanks.

brendlefly62,

You only need one. kmod is preferred as it can load compressed modules, which is a feature you probably don't need.
From memory, knod goes with a udev update but don't quote me on that.

Thanks, NedddySeagoon,
Since I already unmerged module-init-tools, I won't do any more work to try to get it back.
Is it also safe to get rid of modutils (both virtual/ and sys-apps/modutils) once I have kmod?

I emerged gentoolkit and ran a few equeries, and I found these results.

* These packages depend on kmod:
sys-fs/udev-197-r8 (kmod ? >=sys-apps/kmod-12)
virtual/modutils-0 (sys-apps/kmod[tools])

* These packages depend on module-init-tools:
virtual/modutils-0 (>=sys-apps/module-init-tools-3.2)

* These packages depend on modutils:
virtual/modutils-0 (sys-apps/modutils)

* These packages depend on virtual/modutils:
{nothing}

Note that both the kmod-12-r1 and the module-init-tools-3.16-r2 ebuilds both have
RDEPEND=" ...
!sys-apps/modutils


Am I reading this wrong, or is it inconsistent?
i.e. virtual/modutils depends on kmod, module-init-tools, and sys-apps/modutils, but both kmod and module-init-tools both prohibit sys-apps/modutils ...


Is it safe to get rid of virtual/modutils? (that would appear to be where the blockage I referred to came from -- I believe this started when my "emerge -uavDN world pulled in the current module-init-tools (which blocks sys-apps/modutils and kmod) as well as udev-197-r8 upgrade (which pulled in kmod which blocks sys-apps/modutils and module-init-tools)

brendlefly62,

Keep the virtual.
It says
Code:
RDEPEND="|| ( sys-apps/kmod[tools] >=sys-apps/module-init-tools-3.2 sys-apps/modutils )"


Which means its satisfied by either sys-apps/kmod with USE=tools or by >=sys-apps/module-init-tools-3.2 or by sys-apps/modutils

You should not be cleaning your system by hand, except to resolve hard blocks
Run
Code:
emerge --depclean -p
to see packages that portage thinks you don't need.
Pay attention to the list before you run it without the -p option.

Careless use will give you a fright as it an remove your active gcc and leave you with a newer but not yet activated version.
It can remove your kernels from /usr/src but it will leave the .config files behind.

aahh , OK - now I understand.
Thank you very much.

This was a good lesson on how to clear blockers -- as a practical method, clearing the blockers required a bit of research into both:
check the ebuilds of both packages,
use equery to learn what depends on them,
check the ebuilds of those packages depending on the blocking packages,
understand virtuals -- and the options they present,
make an informed choice about which option to employ,

only then feel safe using "emerge --unmerge" to clear the blocker.
